User Exits: Global Variables
When you work with global variables, you need to specify a replacement type to determine how the variable should be replace with a value. In most cases, the replacement types provided by the system (automatic, manual, SAP exit, fixed value from table) will be sufficient.
If you need to have a variable replace using a different method, you can program a user exit for global variables to define your own replacement type.
Example
deriving the current calendar year from the current fiscal year
deriving a 7-digit period from the current period
